Intel compiler doesn't support '__builtin_shuffle'

[applemax82]

Hi,

I failed to build freetype-2.9.1, harfbuzz-1.7.6 and libpng-1.6.34 using 'icc (ICC) 18.0.1 20171018'

The following is my building steps for your reference:

cd libpng-1.6.34 && ./autogen.sh && ./configure --prefix=/usr/local/ --enable-shared && make && make install

cd freetype-2.9.1 && ./configure --prefix=/usr/local/ --enable-shared --with-png=no --with-harfbuzz=no && make && make install

cd harfbuzz-1.7.6 && ./configure CXXFLAGS="-fPIC" --prefix=/usr/local/ --enable-shared --with-freetype=yes && make && make install

cd freetype-2.9.1 && make clean && make distclean && ./configure --prefix=/usr/local/ --enable-shared --with-png=yes --with-harfbuzz=yes && make  && make install

But Intel compiler reported error as shown below:

Does Intel compiler 2019 support '__builtin_shuffle'? Will Intel compiler support '__builtin_shuffle'?

Thanks!

Hi Andrew,

I don't see it yet supports in 2019, but have checked with our developer. I will keep you posted.

Thanks,

Hi Viet,

Any updates on this topic?

I don't have any update yet.

And what now? :)

Thank you, Petr

I dont see it's supported in latest ICC (ICC19.0.5) and also noticed that clang doesn't support __builtin_shuffle either

$ clang t.c -c
t.c:10:11: error: use of unknown builtin '__builtin_shuffle' [-Wimplicit-function-declaration]
     v2 = __builtin_shuffle (v, v1);

@orcsle147:/tmp$ cat t.c
#include <stdio.h>

typedef int myvec __attribute__ ((vector_size (16)));

int foo(void) {
     myvec v = {1,2,3,4};
     myvec v1 = {0,1,1,3};
     myvec v2;

     v2 = __builtin_shuffle (v, v1);
     return 0;
}

What is(are) the types for s0 and s1?

Note, you have specified: -xSSE3 -axSSE3,SSSE3,SSE4.1,SSE4.2

This will restrict you to the 64-bit and 128-bit small vectors.

In the case that you are using 128-bit small vectors, then you could use the emmintrin/xmmintrin intrinsics by way of #define

If you are attempting to use 256-bit vectors, then you haven't specified the AVX instruction set. Note, it is usually counter-productive to specify so many alternate paths.
